3D Mesh Decomposition using Reeb Graphs

Decomposition of complex 3D objects into simpler sub-parts is a challenging research subject with relevant outcomes for several application contexts. In this paper, an approach is proposed for decomposition of 3D objects based on Reeb graphs. The approach is motivated by perceptual principles and supports identification of salient object protrusions. Experimental results are presented to demonstrate the effectiveness of the proposed approach with respect to different solutions appeared in the literature, and with reference to ground-truth data obtained by manual decomposition of 3D objects.
